I also admire all of the conceptual artwork for
Munch's Oddysee, mostly for the nostalgia of a game that never released. I remember looking at some of these snippets—alongside screenshots of those visualisations—in a Playstation magazine back in 2000, marvelling at how huge and immersive Oddworld was becoming.
Here are some of my favourite:
Mugs Against Mudokons
Splinterz
Rainmaker
This style will always be the real
Munch's Oddysee for me. The one we never saw.
(They also remind me of early-internet sprite comics.)
